A Comparative Study of Wear Resistant Properties of Fe-Based Metallurgically Bonded Coatings Applied by Spray and Fuse, PTA, and Laser Cladding

Iron based metallurgically bonded coatings can be an economical method for increasing wear resistance in highly abrasive conditions, such as in oil and gas, mining, and ground engaging applications. The properties of these wear coatings are not only dependent on the chemistry of the coating, but the deposition process significantly affects the microstructure and phase formation. This work explores the different microstructures formed by thermally sprayed, plasma transferred arc (PTA), and laser clad Fe-based coatings and relates these microstructures to the wear performance.
